[0047] In the existing technology, in the early process research and development stage of cylindrical battery welding, in order to explore the appropriate assembly process and prepare for the next large-scale production, the industry usually uses customized non-standard production lines or single-function machines to carry out small-batch trial production of cylindrical batteries. Each welding process requires a customized welding equipment, which takes a lot of time and is costly. The function of a single machine is relatively single and it occupies a large space.

[0048] The invention provides a cylindrical battery welding device.

[0049] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the cylindrical battery welding equipment includes: a first conveying mechanism 100, a second conveying mechanism 200, a carrier turntable mechanism 300 and a welding mechanism 400, wherein the first conveying mechanism 100 is used to convey the welding piece; the second conveying mechanism 200 is used to convey the product to be welded, and the product to be welded corresponds to the welding piece one by one; the carrier turntable mechanism 300 includes a turntable 310 and a welding carrier 320, the welding carrier 320 corresponds to the welding piece one by one, and the welding carrier 320 is arranged on the turntable 310. The rotation of the turntable 310 drives the welding carrier 320 to rotate around the rotating axis of the turntable 310, so that the welding carrier 320 has a first material receiving position, a second material receiving position and a welding position. At the first material receiving position, the welding carrier 320 obtains the welding piece from the first conveying mechanism 100, and at the second material receiving position, the welding carrier 320 obtains the product to be welded from the second conveying mechanism 200. At the welding position, the welding mechanism 400 welds the welding piece on the welding carrier 320 to the product to be welded.

[0050] The first conveying mechanism 100 and the second conveying mechanism 200 can be a conveyor belt conveyor line structure, or a roller conveyor line structure or other conveying mechanism, which is not limited in this embodiment. The first conveying mechanism 100 conveys the welded parts and cooperates with the carrier turntable mechanism 300 so that the welding carrier 320 receives the corresponding welded parts; the second conveying mechanism 200 conveys the products to be welded and cooperates with the carrier mechanism so that the welding carrier 320 structure receives the corresponding products to be welded. According to the welding process of the cylindrical battery, the corresponding welded parts and products to be welded are selected, and the welding jig corresponds to the welded parts and products to be welded, and the welded parts and products to be welded can be obtained respectively and welded by the welding mechanism 400 to realize the corresponding welding process.

[0051] refer to Figure 1 and Figure 2As shown, in the specific implementation process, a plurality of welding carriers 320 are fixed on the turntable 310, and the rotation of the turntable 310 drives the welding carriers 320 to rotate, and the first conveying mechanism 100, the second conveying mechanism 200 and the welding mechanism 400 are distributed along the rotation direction of the turntable 310. In this embodiment, the rotation of the turntable 310 causes the welding carrier 320 to rotate, the first conveying mechanism 100 conveys the welding piece, and the second conveying mechanism 200 conveys the product to be welded, and when the welding carrier 320 rotates to the first receiving position, the welding piece corresponding to the welding carrier 320 is conveyed to the welding carrier 320 by the first conveying mechanism 100, and the welding carrier 320 receives the welding piece. When the rotation of the turntable 310 drives the welding carrier 320 to continue to rotate to the second receiving position, the second conveying mechanism 200 conveys the product to be welded corresponding to the welding piece to the second receiving position, and the welding carrier 320 receives the product to be welded. The turntable 310 drives the welding carrier 320 to continue to rotate to the welding position, and the welding mechanism 400 welds the welding piece to the product to be welded to complete the welding. It should be noted that the welding carrier 320, the welding piece and the product to be welded correspond to each other. In this way, different welding carriers 320 are set on the turntable 310, and the corresponding welding pieces and products to be welded are conveyed by the first conveying mechanism 100 and the second conveying structure respectively. Different welding functions can be realized on the same welding equipment. Compared with one welding machine corresponding to each welding process, it can save R&D costs and save machine space, which is suitable for the early small batch trial production process of cylindrical batteries.

[0052] The turntable 310 of the carrier turntable mechanism 300 rotates so that the welding carrier 320 on the turntable 310 rotates, the first conveying mechanism 100 conveys the welding parts corresponding to the welding carrier 320, the second conveying mechanism 200 conveys the products to be welded corresponding to the welding parts, the welding carrier 320 rotates, and obtains the corresponding welding parts at the first receiving position, and obtains the products to be welded at the second receiving position, and further rotates to the welding position to weld and connect the welding parts and the products to be welded through the welding mechanism 400. Among them, the rotation of the turntable 310 causes the welding carrier 320 to rotate, when the welding carrier 320 rotates to the first receiving position, the first conveying mechanism 100 conveys the welding parts corresponding to the welding carrier 320, and when it rotates to the second receiving position, the second conveying mechanism 200 conveys the corresponding products to be welded, and the welding carrier 320 sequentially obtains the welding parts and the welding carrier 320. In this way, the carrier turntable mechanism 300, the first conveying mechanism 100 and the second conveying mechanism 200 cooperate with each other. The turntable 310 rotates to enable the welding carrier 320 to obtain the corresponding welding parts and products to be welded, so that the welding equipment can realize multiple welding functions to meet the small-batch trial production process of cylindrical batteries. There is no need to design a welding equipment for each welding process, saving cost and space.

[0053] It should be noted that, according to different welding processes, the turntable 310 is provided with different welding carriers 320 and the corresponding welding parts and products to be welded are transported according to the welding carriers 320 .

[0054] refer to Figure 3 to Figure 4 As shown, in one embodiment, there are multiple welding carriers 320, and the multiple welding carriers 320 are sequentially arranged along the circumferential direction of the turntable 310, and each welding carrier 320 obtains the corresponding welding parts and products to be welded. In this embodiment, according to the welding process and process requirements of the cylindrical battery, multiple welding carriers 320 are arranged, so that different welding functions can be realized by starting the device once without replacing the welding carrier 320. Of course, according to the number, sequence and position of the welding carriers 320 set on the turntable 310, the control program designs the first conveying mechanism 100 to convey the corresponding welding parts, and the second conveying mechanism 200 to convey the corresponding products to be welded.

[0055] In another embodiment, further, a plurality of welding carriers 320 are installed on the turntable 310, and the welding carriers 320 can be detachably installed by bolts or the like. According to the cylindrical battery welding process requirements, the corresponding welding carriers 320 can be installed and replaced to achieve different welding functions.

[0056] refer to Figure 5As shown, in a specific implementation process, a variety of welding carriers 320 include but are not limited to positive current collector welding carriers 330, negative current collector welding carriers 340, pole penetration welding carriers 350, and top cover welding carriers 360. Specifically, the turntable 310 sequentially installs the positive current collector welding carrier 330, the negative current collector welding carrier 340, the pole penetration welding carrier 350, and the top cover welding carrier 360, and three groups are provided for example. It should be noted that the positive current collector welding carrier 330 is used to realize the welding process of the positive current collector and the cylindrical battery cell. At this time, the welded part is the positive current collector, and the product to be welded is the cylindrical battery cell. In this embodiment, when the control turntable 310 is rotated so that the positive current collector welding carrier 330 reaches the first material receiving position, at this time, the first conveying mechanism 100 conveys the positive current collector close to the first material receiving position, and cooperates with the positive current collector welding carrier 330 to transfer the positive current collector to the positive current collector welding carrier 330. When the turntable 310 continues to rotate and drives the positive current collector welding carrier 330 to reach the second material receiving position, the second conveying mechanism 200 conveys the cylindrical battery cell close to the second material receiving position, and cooperates with the positive current collector welding carrier 330 to transfer the cylindrical battery cell to the positive current collector welding carrier 330. The rotation continues to rotate and drives the positive current collector welding carrier 330 to the welding position, and the welding mechanism 400 welds the positive current collector to the cylindrical battery cell to complete the welding. It can be understood that after the welding process of the three groups of positive current collectors is completed, the welding process of the negative current collectors is carried out, and the welding is carried out in sequence according to the sequence of the welding carriers 320 on the disc. The number and types of welding carriers 320 are designed according to demand. Of course, the first conveying mechanism 100 and the second conveying mechanism 200 convey the corresponding welding parts and products to be welded.

[0057] In one embodiment, the first conveying mechanism 100 includes a first feeding star wheel 110 and a first discharging star wheel 120, and both are located on one side of the turntable 310. The welding parts are carried on the first support cup 130. At the first receiving position, the first support cup 130 moves from the first feeding star wheel 110 to the welding carrier 320. The welding carrier 320 also has a first discharging position. At the first discharging position, the first support cup 130 moves from the welding carrier 320 to the first discharging star wheel 120.

[0058] The second conveying mechanism 200 includes a second feed star wheel 210 and a second discharge star wheel 220, and both are arranged on one side of the turntable 310. The product to be welded is carried on the second support cup 230. At the second receiving position, the second support cup 230 carrying the product to be welded moves from the second feed star wheel 210 to the welding carrier 320. The welding carrier 320 also has a second discharge position. At the second discharge position, the second support cup 230 carrying the welded parts and the product to be welded moves from the welding carrier 320 to the second discharge star wheel 220.

[0059] It should be noted that the cylindrical battery welding equipment proposed in this embodiment also includes a workbench, and the first feed star wheel 110, the first discharge star wheel 120, the second feed star wheel 210, and the second discharge star wheel 220 are rotatably arranged on the workbench. The first conveying mechanism 100 also includes a first conveyor belt 140 and a first spiral rail 150. The first conveying mechanism 100 conveys the welded parts through the first support cup 130. Specifically, the welded parts are carried on the first support cup 130. The first spiral rail 150 is used for positioning the first support cup 130, so that the first support cup 130 cooperates with the first feed star wheel 110 to realize the transportation of the first support cup 130. The second conveying mechanism 200 also includes a second conveyor belt 240 and a second spiral rail 250. The second conveying mechanism 200 conveys the products to be welded through the second support cup 230. Specifically, the products to be welded are carried on the second support cup 230. The second spiral rail 250 is used to position the second support cup 230, so that the second support cup 230 cooperates with the second feed star wheel 210 to realize the transfer of the second support cup 230.

[0060] In the specific implementation process, the first conveyor belt 140 conveys the first support cup 130 carrying the welded parts to the first spiral track 150. The first spiral track 150 rotates to arrange the first support cups 130 in sequence, maintaining a certain spacing, and ensures that the first feed star wheel 110 rotates to obtain the first support cups 130 carrying the welded parts. When the welding carrier 320 arrives at the first receiving position, the first feed star wheel 110 rotates to convey the first support cup 130 carrying the welded parts to the corresponding welding carrier 320, the welding carrier 320 obtains the welded parts, and the turntable 310 rotates to make the welding carrier 320 convey the empty first support cup 130 to the first discharge position, and cooperates with the first discharge star wheel 120 to convey the first support cup 130 to the first discharge star wheel 120, and is transferred to the first discharge conveyor belt through the first discharge star wheel 120.

[0061] When the turntable 310 rotates to rotate the welding carrier 320 with the welded part to the second receiving position, the second feeding star wheel 210 rotates to convey the second support cup 230 carrying the product to be welded to the welding carrier 320, and the welding carrier 320 obtains the second support cup 230 carrying the product to be welded. The welding carrier 320 drives the welded part to be welded close to the product to be welded, and the turntable 310 rotates to rotate the welding carrier 320 to the welding position, and the welding mechanism 400 welds the welded part to the product to be welded.

[0062] The turntable 310 rotates to rotate the welding carrier 320 to the second discharge position, and cooperates with the second discharge star wheel 220 to transport the second support cup 230 carrying the welding parts and the products to be welded to the second discharge star wheel 220, and then transported by the second discharge star wheel 220 to the second discharge conveyor belt.

[0063] In one embodiment, the second conveying mechanism 200 also includes a third discharge star wheel 260, which is disposed between the first discharge star wheel 120 and the carrier turntable mechanism 300, and is used to receive the second support cup 230 conveyed by the carrier turntable mechanism 300 and convey the second support cup 230 to the first discharge star wheel 120.

[0064] Specifically, the turntable 310 rotates to drive the welding carrier 320 to the second discharge position from the welding position. At the second discharge position, the product is transferred from the third discharge star wheel 260 to the second discharge conveyor belt, thereby realizing automatic control to ensure the yield of the product. It can be understood that the third discharge star wheel 260 cooperates with the welding carrier 320 and the second discharge star wheel 220 to realize the transfer through the second support cup 230.

[0065] In one embodiment, the welding carrier 320 includes a main body and a clamping component 321 and an adsorption component 322 arranged on the main body. The adsorption component 322 is located above the clamping component 321. The clamping component 321 includes clamping claws, which respectively clamp the first support cup 130 and the second support cup 230 so that the adsorption component 322 adsorbs the welding part.

[0066] In addition, the cylindrical battery welding equipment also includes a visual guidance device 500, which is used to collect information about the welded parts and the products to be welded, and transmit it to the welding mechanism 400. The visual guidance device 500 can be a camera or a CCD camera, etc., which is used to guide the welding mechanism 400 to improve the stability and quality of welding.

[0067] The present invention also proposes a cylindrical battery welding method, which is applied to cylindrical battery welding equipment. The specific structure of the cylindrical battery welding equipment refers to the above embodiment, and at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here one by one.

[0070] The second conveying mechanism 200 conveys the product to be welded corresponding to the welded part to the carrier turntable mechanism 300, and the welding carrier 320 that obtains the welded part obtains the product to be welded;

[0071] The welding mechanism 400 welds the corresponding welding piece to the product to be welded;

[0072] The welding carrier 320 transports the welded parts and the products to be welded to the second transport mechanism 200 .

[0073] The first conveying mechanism 100 conveys the welded part to the carrier turntable mechanism 300. At this time, the turntable 310 rotates so that the corresponding welding carrier 320 arrives at the first conveying mechanism 100 at the same time. The two cooperate, and the welding carrier 320 obtains the welded part; the turntable 310 continues to rotate to the second conveying mechanism 200. At this time, the second conveying mechanism 200 conveys the product to be welded to the carrier turntable mechanism 300. The two cooperate, and the welding carrier 320 obtains the product to be welded again. Then, the turntable 310 continues to rotate, and the welding carrier 320 arrives at the welding mechanism 400 for welding.

[0074] In the specific implementation process, according to the welding process requirements of the cylindrical battery, the corresponding welding parts and products to be welded are selected, and the first conveying mechanism 100 and the second conveying mechanism 200 are controlled to cooperate with the corresponding welding carrier 320, so that transportation and welding are coordinated to automatically complete the welding process. A plurality of welding carriers 320 are arranged circumferentially on the turntable 310 of the carrier turntable mechanism 300. The plurality of welding carriers 320 can be of the same type or of different types. The two conveying mechanisms can be controlled to cooperate in conveying the corresponding welding parts and products to be welded, thereby realizing multiple welding functions, reducing the design of a single machine, and saving costs.

[0075] In one embodiment, the first conveying mechanism 100 conveys the welded part to the carrier turntable mechanism 300, and the welding carrier 320 corresponding to the welded part obtains the welded part, including:

[0076] The rotating disk 310 rotates to drive the welding carrier 320 to rotate to the first material receiving position, and the first feeding star wheel 110 conveys the first support cup 130 carrying the welding part corresponding to the welding carrier 320 to the welding carrier 320, wherein the adsorption component 322 of the welding carrier 320 adsorbs the welding part, and the clamping component 321 of the welding carrier 320 clamps the first support cup 130;

[0077] The rotating disk 310 rotates to drive the welding carrier 320 to rotate to the first material discharging position, and the clamping assembly 321 conveys the first support cup 130 to the first material discharging star wheel 120 .

[0078] Specifically, the first conveying mechanism 100 conveys the welded part to the carrier turntable mechanism 300, the turntable 310 rotates to drive the corresponding welding carrier 320 to rotate to the first receiving position and absorb and obtain the welded part conveyed by the first conveying mechanism 100, and the turntable 310 drives the welding carrier 320 to continue to rotate; the second conveying mechanism 200 conveys the product to be welded, the turntable 310 rotates to drive the welding carrier 320 to the second receiving position, and clamps and obtains the product to be welded conveyed by the second conveying mechanism 200, and it should be noted that the welded part is located above the product to be welded. The rotation of the turntable 310 causes the welding carrier 320 to continue to rotate to the welding position, and in this process, the welding carrier 320 also makes the welded part close to the product to be welded, so that the welding mechanism 400 can weld. The welding carrier 320 rotates to the welding position, and the welding mechanism 400 welds the welded part to the product to be welded. In the specific implementation process, the welding mechanism 400 uses a laser welding device to perform laser welding. After welding is completed, the turntable 310 continues to rotate, so that the welding carrier 320 conveys the welded parts and welded products through the second conveying mechanism 200 , and the turntable 310 continues to rotate, so that the welding carrier 320 performs the next welding process.

[0079] The second conveying mechanism 200 conveys the product to be welded corresponding to the welded part to the carrier turntable mechanism 300, and the welding carrier 320 of the welded part obtains the product to be welded, including:

[0080] The turntable 310 rotates to drive the welding carrier 320 to rotate to the second material receiving position, and the second feeding star wheel 210 transports the second support cup 230 carrying the product to be welded corresponding to the welding carrier 320 to the welding carrier 320, wherein the clamping assembly 321 of the welding carrier 320 clamps the second support cup 230, and the adsorption assembly 322 drives the welding part to approach the product to be welded.

[0081] The welding parts are carried on the first support cup 130, and the products to be welded are carried on the second support cup 230, which can play a protective role on the one hand, and on the other hand, the welding equipment can transport a variety of welding parts and products to be welded through the support cup, thereby improving the applicability of the equipment.

[0082] Furthermore, the welding carrier 320 transports the welded parts and the products to be welded to the second transport mechanism 200, including:

[0083] The rotating disk 310 rotates to drive the welding carrier 320 to rotate to the second discharge position, and the clamping assembly 321 transports the second support cup 230 carrying the welding parts and the products to be welded to the second discharge star wheel 220 .

[0084] The turntable 310 rotates so that the welding carrier 320 sequentially obtains the welded parts from the first receiving position, outputs the first support cup 130 from the first discharging position, obtains the product to be welded from the second receiving position, performs welding from the welding position, outputs the second support cup 230 from the second discharging position, and the welded parts and the product to be welded after welding. In this way, it can be understood that the first conveying mechanism 100, the second conveying mechanism 200, and the welding mechanism 400 are respectively arranged around the carrier turntable mechanism 300, and the welding mechanism 400 is located between the second feeding star wheel 210 and the second discharging star wheel 220 of the second conveying mechanism 200. Through reasonable arrangement, the corresponding processes are completed in sequence, and multiple welding functions are completed in sequence.

[0085] In one embodiment, before the welding mechanism 400 welds the corresponding welding part to the product to be welded, and during the process of the turntable 310 rotating to drive the welding carrier 320 to rotate from the second feed star wheel 210 to the welding mechanism 400, the visual guidance device 500 obtains information about the welding part and the product to be welded, and the welding mechanism 400 welds the welding part and the product to be welded according to the information.

[0086] In the specific implementation process, during the rotation of the turntable 310, the visual guidance device 500 first obtains information about the welded parts and the products to be welded, and transmits it to the control system, which generates a corresponding welding command and sends the welding command to the welding mechanism 400 for welding to improve the welding effect. In addition, the control system can also monitor whether it is a good product based on the information obtained by the visual guidance device 500 to improve the yield of the product.

[0087] In the specific implementation process, when the welded part is a positive electrode collector, the first conveying mechanism 100 conveys the first support cup 130 carrying the positive electrode collector to perform the welding process, the welding carrier 320 of the turntable 310 is a positive electrode collector welding carrier 330 and cooperates with the first conveying mechanism 100 and the second conveying mechanism 200, and the second conveying mechanism 200 conveys the second support cup 230 carrying the cylindrical battery cell to perform the welding process, thereby realizing the positive electrode collector welding of the cylindrical battery. It can be understood that other welding functions refer to the above process, and the required welding carrier 320, the first conveying mechanism 100 and the second conveying mechanism 200 are sequentially set on the turntable 310 and the welded parts and products to be welded that are required and corresponding.
